My Keys were stolen out of my purse, I had them on a long like nike key chain, and the chain cloth part was hanging out of my purse. the plice believed they wanted to steal my car, but I was in a secure paying parking structure. Well they were stolen and I had a mess on my hands had to have car towed, then had to buy new key and then have it all re done. It cost me a whole lot of money between the keys and the new rekeying and the rental car.

It was a total nightmare and my car has had problems ever since.
So be careful, they are not cheap keys.
